You have landed on an unknown planet, Newtonia, and want to know what objects will weigh there. You find that when a certain tool is pushed on a frictionless horizontal surface by a 12.5 N force, it moves 16.5 m in the first 2.30 s, starting from rest. You next observe that if you release this tool from rest at 11.0 m above the ground, it takes 2.88 s to reach the ground.
a. What does the tool weigh on Newtonia?
b. What would it weigh on Earth?
